ST3237EBPR

ST3237EBPR is a ±15KV ESD protected, RS-232 transceiver with stand-by. This 3V to 5.5V powered EIA/TIA232 and V.28/V.24 communication interfaces high data-rate capability and enhanced electrostatic discharge (ESD) protection at ±8kV using IEC1000-4-2 contact discharge and ±15KV using human body model (HBM). The other pins are protected with standard ESD protection at ±2kV using HBM method. This device has a proprietary low-dropout transmitter output stage providing true RS-232 performance from a 3V to 5.5V supply using a dual charge pump. This device is guaranteed to run at data rates of 250Kbps in the normal operation mode and 1Mbps in the very high speed operation mode while maintaining RS-232 output levels.
